What is the best aquarium automatic fish feeder

My Eheim auto feeder just fell into my aquarium. I could buy the same kind again, and I am likely to do so. Before doing that I would love some suggestion of a better option.

I have a 36g small aquarium with few fish in.

I am traveling a lot so an auto feeder is a requirement, I am looking for the best alternative. Cost is not a priority.

Thanks for your suggestions
